MACHINE FO R STUFFING MATTRESSES STEEGIFICATION forming part of Letters Patent No. 591,077, dated October 5, 1897. Application filed May 21, 1897- Serial No. 637,549. (No model.)

To all whom it may concern:

Be it known that I, AMENZO GRIFFITH, a citizen of the United States, and a resident of Springfield, in the county of I-Iampden and State of Massachusetts, have invented certain new and useful Improvements in Machines for Stuffing Mattresses, of which the following is a specification.

This invention relates to improvements in machines for stuffing mattresses of the class in which there is comprised a broad shallow box or receiver having a movable cover or covers, a movable gate closing one end of the box and separating it from a spout, and a stuffing-bar and means for imparting thereto a motion in the direction of the length of the box for expelling the compressed excelsior or other mattress-filling material, the same being also adapted to be withdrawn in a reversed direction after its forward thrust.

The present invention relates 'to improved combinations of parts comprised in a mattress-stuffing machine such as has been above in a general way referred to; and the invention consists in constructions and combinations or arrangements of parts, all substantially as will hereinafter fully appear, and be set forth in the claims, all to the end of simplifying the machine and cheapening and ren dering the same more satisfactory and available and increasing its capability for rapidly performing its required work. My improved mattress-stuffing machine 'is illustrated in the accompanying drawings, in l which- Figure 1 is a central sectional elevation taken lengthwise of the machine. Fig. 2 is a plan View of the machine.

Similar letters and figures of reference indicate corresponding parts in both of the views.

In the drawings, A represents the frame of the machine, comprising opposite posts or standards 10 10, the paired separated top rails 12 and 13, the bed a, forming the bottom of the stuffing-box E, supported by and connecting the opposite pairs of the rails above their lowerends, and suitable cross ties or bars, as let 15. l

B and 0 represent the divided movable cover-sections of the mattress-stuffing box E, the said sections or members beingpivoted to the frame, as seen at 16 and 17, and are operated by novel means, which will be hereinafter particularly referred to.

One end of the mattress-stuffing box is closed by the movable gate 1), this gate dividing the chamber comprised within the stuffion-wheel 23 on the driving-shaft 24, which shaft has thereon the three pulleys '5, i and i two being loose and the other one fixed on the driving-shaft.

An open belt and a cross-belt are provided, as indicated at j 3' Fig. 1, which may run on the loose pulleys, either one thereof being adapted to be shifted onto the fixed pulley i at one time, so as to give a running motion to the chains g (duplicated) in either direction desired, which chains have, as seen at 25, a connection with the frame f, on'which the stuffing-barD is supported and in unison with which said stuffing-bar moves. 1

The space and boundaries between the lower and upper sides of the horizontal rails 12 13 of the frame A constitute ways for the bars G, mounted therein for longitudinal slide, both of said bars at one end being united by the cross rod or shaft k, on which, next to the extremities ofthe bars g, are journaled the flanged rollers m m, which run along the upper side of the horizontal rail 13, serving as trucks for the said bars G. Each of the said rails 13 has within its upper side a longitudinal groove 30, in which a stud, rib, or projection 32, extended below the under side of the bar G, has a sliding fit.

The paired bars H H are pivotally hung opposite each other from the aforesaidcross rod or shaft is, which unites the pair of bars G, the lower ends of these depending bars H being pivoted, as indicated at 33, to the crosscleat 34, which is EtffiXGd to the upper side of the section B of the cover.

A sprocket-chain J, which has its one end 85 affixed or anchored to the cross-rod 7t, extends from this connection around the sprocket-wheel n, which is on the cross-shaft 0, supported horizontally in journals 37 37 at the right-hand upper corner of the frame, this chain thence continuing in an oblique direction downwardly to a connection, as seen at 39, with the cross-cleat 40, which is affixed to the upper side of the cover-section near its edge, which meets the edge of the coversection B.

The reciprocatory movement is imparted to the paired bars G G by means as follows: Paired sprocket-wheels p are affixed at the ends of the shaft 0,and paired sprocket-wheels q are also afiixed at the opposite ends of the cross-shaft r at the top of the machine near the end of the latter, opposite that at which the shaft 0 is mounted, and the duplicated sprocket-chains 3 run around said sprocketwheels 19 g, each of these chains being affixed, as seen at 42, to the bar G. The shaft 1" has thereon the gear-wheel t, in mesh with which is the pinion u on the shaft 1;, which has thereon the two loose pulleys c 6 one of which is driven in one direction by the open belt e while the other is driven in the opposite direction by the cross-belt 6 which belts are understood as driven from a pulley on any suitable or available overhead power-driven shaft. Each of these pulleys e c has 011 its hub a clutch member a and a coactin g double clutch member 'w is splined on the shaft 40 and may be thrown into clutch with either of the pulleys c or 6 whereby the shaft 1 may be rotated in either direction and the chains .9 8 caused to have a corresponding travel 1011- gitudinally forward or backward and the said bars G G therewith.

x represents a slide-rod supported in guide supports for movement crosswise of the ma chine and having engaged therewith the pivoted lever 00 and this cross-rod carries the fixed arm 00 which engages in the groove 45 in the double clutch member 10, all whereby by proper manipulation of said lever 00 the shaft may be out of clutch or in clutch at one time with either of the pulleys c e to be driven in the one or the other direction to insure the proper travel of the bars G G, as

desired.

Now, of course, it will be plain that with the cover-sections B 0 down and the parts correspondingly in the positions shown in the drawings and the clutches operated to rotate the shaft 1; to cause the chains 8 s to move the bars G G to the left the chain J will be so drawn upon as to cause the cover-section O B, will, simultaneously with the elevation of the cover-section 0, effect the placing of thel cover-section B in the nearly-upright position indicated by the dotted line B It will be apparent from the construction and operativeness of the various contrivances here illustrated that the mechanism at the top of the machine may be operated to elevate the cover-section, and while the clutch w is thrown out the mattress-filling may be placed and heaped up in the box, and then the clutch w is thrown into the other adjacent pulley, (opposite the one which was in clutch when the covers were raised,) whereupon the covers will be lowered, and as the bars H II assume their vertical position they act as toggles or compression'bars to force the'covers into a horizontal position and suitably compress the mattress-filling material, \Vhen the covers are in their horizontal positions, the clutch is again thrown out, and the bar G has its endwise traveling movement imparted thereto through the pulleys and gearing described, it ejecting the compressed filling through the spout into the mattress, the gate having been slid from its closing position, and then the belts j and j are shifted to cause the stuffing-bar D to be moved to its original position, whereupon the mechanism at the top of the machine is again operated to effect the elevation of the cover-sections to permit the introduction into the box of another quantity of the stuffing material, when the operations are repeated as before.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a mattress-stuffing machine, the combination with a stuffing-box and two hinged cover-sections therefor, of a bar and supports on which the same is mounted to move, wheels 1) q and chains or like flexible appliances running around said wheels and having a connection with said bar, means for imparting rotary movements to one of said wheels, a supporting and guiding wheel at, a chain or like flexible connection secured to said bar, running around said wheel n and connected to one of the cover-sections, and the bar H pivotally sustained by the said movable bar and pivotally connected to the other cover-section, substantially as described. 2.
